Jim Walker <[EMAIL PROTECTED]> ：I will go a step further and suggest that the input signal should be 3.3V. Not only do you need to turn on the bottom N-channel device, you must also turn off the upper P-channel device. The signal must be closer to the rail than the threshold voltage which is frequently quite low. CMOS inverters are not normally used as voltage amplifiers but rather as buffers (current gain) or to reverse the polarity of the signal.
I hope that helps.

Can you give it a try in your computer? It’s not difficult at all!
